- Application filed May 2, 1914.. Serial No. 836,011.

To all whom, it may concern:

Be it known that I, JOHN J. SEVERIN, citizen of the United States,residing at darnesboro, in the county of Cambria and State ofPennsylvania, have invented certain new and useful Improvements inResilient Wheels, of which the following is a specification, referencebeing had'to the accompanying drawings.

This invention relates to improvements in vehicle wheels, and moreparticularly to that class of wheels which are resilient.

An object of this invention is the provision of a resilient wheel, thewheel including a plurality of spring spokes disposed between the huband the rim, each of the spokes comprising a pair of telescopingsections.

A further object of this invention is the provision of a spring wheelincluding a hub and a rim between which spring spokes are interposed,each of the spokes including a pair of telescoping sections, the outersection of each spoke which is secured to the rim being capable ofslight circumferential movement with relation to the inner sections ofthe spokes to prevent undue strain from being imposed upon thehorizontally positioned spokes when the wheel is revolving.

\Vith these and other objects in view, my invention consists in thenovel construction, combination, and arrangement of parts to behereinafter more fully described, claimed, and illustrated in theaccompanying drawing. in which,

Figure 1 is a fragmentary side elevation of my improved resilient wheel,partly in section; and Fig. 2 is a sectional view on the line of Fig. 1.

Referring more particularly to the drawing, the numeral 1 designates thehub. E2 the rim, and 3 my improved spring spokes which are interposedbetween the hub and the rim. Each of the spokes comprises an innertubular section 4' and an outer tubular section 5, the inner end of theouter section of each spokebeing reduced for telescoping engagementwithin the outer end of the inner section of the spoke. The inner end ofthe inner section of each spoke is closed, and projecting longitudinallyfrom the closed inner end of each spoke is a reduced apertured lug (l. Aplurality of elongated transversely extending recesses 7 is formed inthe periphery of the hub, the recesses being adapted to receive thereduced apertured ity of the outer lugs of the inner sections of thespokes, and disposed through the hub and the openings in the lugs aresuitable fastening devices 8 by means of which the inner sections of thespokes are secured to the hub. A plurality of threaded openings 9 isformed in the rim in radial alinement with the recesses 7 in the hub,and the outer end of each of the outer sections of the spokes isthreaded as at 10, for engagement in one of the threaded openings in therim, whereby the outer sections of the spokes are secured to the rim.The outer end of each outer section is also interiorly threaded toreceive a threaded head 11 which is adapted to close the outer end ofthe section. Each of the heads 11 is provided with an outwardlyprojecting reduced angular extension 12 for engagement by a suitabletool (not shown) whereby the 'heads may be turned into or out of thespokes.

Projecting outwardly from the closed end of each inner section is a stem13, the free end of the stem projecting beyond. the end of the innersection for engagement within the inner end of the outer section of thespoke. Mounted within the outer section of each spoke to hear at itsouter end against the head 11 is a helical spring 11, the inner end ofthe spring being engaged against the extremity of the stem 13. anddisposed within the outer end of each inner section around the stem 13is a similar helical spring 15, one end of the spring 15 engaging theclosed end of the inner section, and the outer end of the spring 15engaging the inner extremsection. The opposite faces of the sections ofthe spokes at their opposing ends, which face in the direction of thelongitudinal plane of the hub. are flattened as at 16. so that when thesections are teleseoped. the flattened faces engage each other toprevent transverse. rocking of the rim with relation to the hub. Asclearly shown in Fig. 2 of the drawing. the rounded portions of thetelescoped sections are spaced from each other in a directioncircumferentially of the wheel, so that the outer sections of the spokesare allowed to rock circumferentially of the wheel with relation to thehub to relieve the spokes of abnormal strain and to allow the rim tomove slightly with relation to the hub, when the wheel is revol vingover the ground.

In the practical use of my improved wheel. when the portion of the rimengaging the ground strikes an obstruction in the roadop nings herein tothreadably receive the way, the'rim will be forcedt upwardly toouterends of the outer members of the 5 ward the hub against the tension ofthe spokes, said outer members being interiorly springs 14 and 15 sothat the springs will threaded at their outer ends, heads thread- 5absorb the shock ordinarily imposed upon ably'mounted in the outer endsof the outer the-vehicle body (not shown). The tension sections, stemsprojecting outwardly from of the springs l l maybe readily adjusted bythe inner end walls of the inner members, 0
